TO ALLWHOM IT MAY CONCERN: I v I Be it known that I, WALTER B. NoYs, of' Dorchester, in the connty of Grafton, and Stute of'Ne\v.jIIomp shire, have invented eertainneiv and useful' Improvements in Saw-Guides and Jointers; sind I dqherebyfieelere thntfthe foilowingis a f ull, clear, and exact description theroof,rei`ereiice being had to the oceornpnnyiiig druivugs'Land to the letters'of reference mnrked thereon.\which form'epnrt oi` this specic'atiomin vvhich.

Figure 1 represents eperspeetive' View of -my invention.-

Figue 2 is a plan view of the joint'er.

Figure 3 is n plan view ofthe clutch. K

The letter A designatesthe saw frnme, B represents the. snmnmi Ctho vshnfft on which the saw is fatstoned. D represents an'arm of the jointer-bed, which may-be permanently fastened to the cxirringe, in theinnnnerehown in 5g. 1, -thesaid arm Dy being bent out-wards at right angles; toform a. bed, j, for the jointei',g.\j Thejointer g hns' a. longitudinal groove iu-its uppersurfoe, to receive the slide h, (see fig. 1,-) nndjs furnished nt one end with projections s, amd at the other end with sheath t, whiohissl designed to hold the vfiieueedlfor regulating the` snivlteeth. When the file is in position it will-be held irmly by screwn. In order to move the slide neer to or further froru'the saw, the joint-er is formed with the shoulder z", through which the sereiv n is mudo to pass, the end of s aid screw operating on projection s on slide L.. trepresents nclutch, which'is designed to control the vibration of-the snw when said sew is under the :Lotion oi' the file, und hztvingperformtl this; oiioe-cain'bc removed.; The clutch k is placed on the horizontal metal plate L, nud works on the .pivot :Vithe Suid clutch being regulated in reference to the sztw by the screws P P.

vibration of the sew,4 and secondly, in bringing thele in eheeth inicontact with the points of thelongestteeth,

' The operation of my invention is simple., und consists, first, in Anlfljusting the ,clutch` h so sto control the K,

Vand then, bypperatingth'e s crew m, ns tho` longest teeth are suecessively ont oil', the 'teeth nre reduced to the required standard.

Having thus described my invention, what I cia'gim as new, and desire to secure by. Le'tter Patent, is- The j ointer g', constructed and operating as und for the purpose set forth. :In testimony that I claim the foregoing as my o'wu, I aiix signature in presenceoi` two witnesses.
